coupling and fully into inducer housing connection until it
bottoms on the internal stop. Tighten both clamps to secure the
pipe to inducer housing. Tighten the clamp screws to 15 in.-lb.
of torque.
5. Install casing hole filler cap (factory-supplied in loose parts
bag) in unused vent pipe casing hole.
VENT EXTENSION PIPE
Some furnaces are supplied with a PVC vent extension pipe
(2-in. diameter by 12-in. long). This pipe has a built-in
channel to assist vent condensate disposal. When this vent
extension pipe is supplied, it must be used to connect the field
vent pipe to furnace inducer housing.
NOTE: See label on vent extension pipe for proper installation.
This pipe may be shortened if an elbow is used to connect vent
extension tube to field-installed vent pipe.
6. Working from furnace to outside, cut pipe to required
length(s).
7. Deburr inside and outside of pipe.

8. Chamfer outside edge of pipe for better distribution of primer
and cement.
9. Clean and dry all surfaces to be joined.
10. Check dry fit of pipe and mark insertion depth on pipe.
NOTE: It is recommended that all pipes be cut, prepared, and
preassembled before permanently cementing any joint.
11. After pipes have been cut and preassembled, apply generous
layer of cement primer to pipe fitting socket and end of pipe
to insertion mark. Quickly apply approved cement to end of
pipe and fitting socket (over primer). Apply cement in a light,
uniform coat on inside of socket to prevent buildup of excess
cement. Apply second coat.
12. While cement is still wet, twist pipe into socket with 1/4 turn.
Be sure pipe is fully inserted into fitting socket.
13. Wipe excess cement from joint. A continuous bead of cement
will be visible around perimeter of a properly made joint.
14. Handle pipe joints carefully until cement sets.
